I recently compiled gdb 3.5 with Michael Bloom's stabs-in-coff patches
on a 386 machine running Interactive Unix 2.2, which claims to be
POSIX-compliant.   Here are the changes I needed to make.  I don't think
any of them are particular to the stabs-in-coff stuff.

ISC 2.2 has some support for signals, and so SIGTSTP is defined by their
<signal.h>.  But they don't supply sigsetmask, and I didn't want to try
to figure out what their equivalent was.  Therefore, I simply kludged.

Also, in malloc.c, <sys/vlimit.h> apparently defined some LIM_DATA
symbol.  Since this system doesn't have vlimit.h, I had to hack around
that.  Anyway, surely gdb should use Mike Haertel's newer malloc...
